13 Claims.

This invention relates to liquid dispensing apparatus and moreparticularly to mechanism for indicating and registering the quantitiesof liquid dispensed by such an apparatus.

One object of the invention is to provide simple and eflicient means forregistering the quantity ofliquid delivered by the apparatus and forresetting such registering mechanism to its initial position at the endof each delivery operation.

A further object of the invention is to provide such a mechanism inwhich the indicating device and the registering device may besimultaneously reset to their initial positions by the manipulation ofthe single operating mechanism and which will have means for permittingthe continued movement of the operating mechanism when one of saiddevices reaches its initial position in advance of the other.

A further object of the invention is to provide such a mechanism withmeans for automatically preventing the operation of the resettingmechanism while the delivery mechanism is in operation and forpreventing the operation of the delivery mechanism during'the resettingoperation. Other objects of the invention will appear as the apparatusis described in detail,

In these drawings I have illustrated one embodiment of my invention andhave shown the same as applied to dispensing apparatus of the type knownas a meter pump, in which the liquid delivered is measured by a meterand the meter operates the indicating and registering devices. 5 It willbe understood, however, that this particular mechanism has been chosenfor the purposes of illustration only and that the invention may takevarious forms and may be utilized with dispensing apparatus of variouskinds.

The particular dispensing apparatus here illustrated comprises a rotarypump i5 mounted within a housing l6 and driven by an electric motor H,the operation of which is controlled by a switch 18. The pump drawsliquid from a suitable reservoir, such as the usual underground tank,and delivers the same through a pipe I 9 to a meter 20. The liquidpasses from the meter through adischarge pipe 2| to a delivery hose 22,a portion only of which is shown. Any suitable means may be provided foractuating the switch and thus controlling the operation of the deliverymechanism. In the present instance, I have employed a switch actuatingdevice simi-. lar to that shown in the Hanna and Bradley applicationfiled September 5, 1930, Serial No. 479,870 new Patent No. 1,974,649. Arigid nozzle supporting member 23 is mounted on a fixed part of theapparatus within the housing l6 and extends beyond that housing toreceive and support the nozzle 24 at the discharge end of the hose.

A lever 25 is pivotally mounted near the inner end of the supportingmember 23 and is connected by a rod 26 with the switch IS. The outerportion of the switch actuating lever 25 is movable into a positionimmediately above and in contact with the'supporting member 23 and intoa position spaced from the same. The connection between the lever andthe switchis such that when the lever is in contact with or adjacent tothe supporting member 23 the switch will be closed and when the lever isspaced from the supporting member the switch will be open. The outerportion of the lever is preferably tapered and-prevents either thenozzle or the hose being hung upon the support while the switch isclosed. When the nozzle is on the support the lever is held in itsspaced position and the switch cannot be closed.

Mounted above the meter 20 is a device to indicate the quantities ofliquid delivered, this device being of such a character that it willindicate gallons, or other units of measurement, and fractions thereof,and it is driven from the meter. As here shown, see Figs. 1, 5 and 6, asupplemental frame or supporting bracket 21 is mounted in the housingabove the meter and provided with uprights 28 in which is journaled ashaft 29 having secured thereto a gear 89 which meshes with a pinion 82carried by the meter driven shaft 88, the gear ratio being such thattheshaft 28 will make one complete rotation for each gallon, or otherunit, of liquid delivered. The shaft extends beyond the housing and hassecured thereto a pointer 84 which travels over a dial a mounted on theouter side of the housing I6 and graduated in gallons, or other units ofmeasurement, and in fractions thereof. In the present instance, theindication is made on both sides of the housing and the shaft therefor.extends beyond both sides of the housing and is provided at each endwith a pointer 84. These pointers make one complete rotation for eachgallon delivered and the reading is upon the fractional graduations onthe dial, that is, the graduations and Rotatably mounted on the shaft 28near each end thereofare sleeves 85 and 85 which extend through therespective walls of the housing and have secured to their outer endspointers 81 adapted also to travel over the faces of the dials and toindicate thereon the gallons of liquid delivered. Each sleeve isprovided at its inner end with a gear 88 which meshes with a pinion 88on a countershaft 49 rotatably mounted in the uprights 28 and preferablyarranged above the shaft 28. The shaft 28 has secured thereto. adjacentto one of the gears 88, a trip arm or pawl 4! arranged to engage andactuate a star wheel 42 secured to the shaft 40. The trip arm 4| beingrigidly secured to the shaft 28 it will be apparent that it will engageand actuate the star wheel once for each rotation of the shaft 29 andthe ratio of the gears 88 and 88 is such that the indicating pointers 81will be advanced a distance equal to one gallon on the face of the dialfor each rotation of the shaft 29. The sleeve 85 is connected with theshaft 29 by a one-way clutch which will permit the shaft to rotateforwardly with relation to the sleeve and will cause the sleeve torotate with the shaft when the latter is moved in a reverse direction.As here shown, this one-way clutch is in the form of a spring pressedpin 43 slidably mounted in the sleeve 35 and adapted to enter a recess44 in the shaft 29, this recess having an abrupt forward wall and atapered rear wall so that when the shaft is rotated forwardly the pinwill ride out of the recess and when the shaft is reversed the abruptwall of the recess will engage the pin and cause the sleeve to rotatewith the shaft. The clutch is so arranged that when the shaft picks upthe sleeve the pointers 84 and 81 will be in alinement and will movetogether toward their initial or zero positions. The rotation of theshaft 29 and sleeve 85 in a reverse direction so changes the relativepositions of the star wheel and the trip arm 4i, that, when the pointersreach their initial positions, the trip arm will engage the end of atooth of the star wheel and the movement of the trip arm and the shaftwill be positively stopped. A detent pawl 45 is held normally inposition by a weighted arm 48 to prevent forward movement or overthrowof the star wheel42 when the latter is moved forward one step by thetrip arm 4i and, further, to prevent forward movement of the star wheelwhen the trip arm is in disengaged relation to the star wheel. The triparm 4| is provided with a laterally extending pin 41 to engage and liftthe arm 46 immediately preceding contact of the trip arm with a tooth ofthe star wheel 42, thus lifting the detent pawl 45 out of engagementwith the star wheel and permitting the trip arm to move the star wheelforward only one step. Just prior to disengagement of the trip arm 4|from the star wheel 42 during normal continuance of the forwardmovement, the pin 41 will permit the arm 48 to drop and the detent pawl45 to re-engage the star wheel 42 to prevent further forward oroverthrow movement of the star wheel until the trip arm has againreached a point immediately preceding engagement with the star wheel.tional retarding device 48 affords additional re sistance to theoverthrow of the star wheel. Reverse movement is imparted to the shaft28, for resetting the indicating devices, in a manner to be hereinafterdescribed. It is desirable that the shaft 29 shall rotate in a reversedirection independently of the meter driven shaft 88. For this purposethe gear 88 may be connected with the shaft 29 by a suitable clutch 85awhich is here shown as a friction clutch which will cause the shaft tobe rotated by the gear when the latter is actuated but will slip andpermit the shaft to rotate in the gear when the shaft is rotated and thegear held against movement.

A device is also provided for registering the quantities of liquiddelivered so that a printed record maybe taken therefrom and thisregistering device is, in the presentinstance, contained within asupplemental housing 48 mounted on a bracket 50 arranged at one side ofthe apparatus. The registering apparatus comprises a counter shaft 5i onwhich is rotatably mounted a quart counterwheel 52 having connectedthereto a ratchet wheel 58. Also mounted on the shaft 5i is the gallonscounterwheel 54 which is provided with an elongated hub 55 to which issecured a ratchet wheel 56. The two counterwheels are separate andindependently operable, they being preferably separated by a stationaryspacing member 56a, and in the present instance both counterwheels areprovided with printing type. The shaft 5! may also carry other typewheels I56 which may be actuated manually or otherwise to recordadditional data but form no part of the present invention. Arrangedparallel with the countershaft 5i, and preferably below the same, is ashaft 51 which is driven in accordance with the quantities of liquiddelivered by the apparatus. In the present arrangement a shaft 58extends from the housing 49 into the housing It and has at its inner enda beveled gear 59 which meshes with the gear 88 on the shaft 29. Securedto the shaft 58, within the housing 48, is a spur gear 50 which mesheswith a second spur gear 6! which in turn is connected with the shaft 51through an overrunning clutch, such as an ordinary roller clutch. 62,which is arranged to cause the shaft 51 to rotate with the shaft 55 butto permit. the shaft 51 to rotate forwardl with relation to the shaft58. Connected with and operated by the shaft 51 are suitable devices foradvancing the type counterwheels in accordance with the quantity ofliquid delivered. The actuating device for the quarts counterwheel, asshown in Fig. 2, comprises a pawl carrier 58 mounted on the shaft 51,for pivotal movement and for sliding movement transversely to the shaft,the pawl carrier preferably having a longitudinal slot through which theshaft extends, as shown in dotted lines in Fig. 2. At its upper end thispawl carrier is provided with a. nose, or pawl, 64 to engage the ratchetwheel 58 of the quarts counterwheel. At its lower end the pawl carrier Africhas a laterally extending arm 85 which is acted upon by a spring 66,which spring serves to impart pivotal movement to the pawl carrier tohold the pawl in engagement with the ratchet wheel and to impartlongitudinal downwardly sliding movement thereto. Rigidly secured to theshaft 51 is a four-lobe cam 61'arranged to engage a projection 68 on thepawl carrier'and move the same upwardly against the tension of thespring 68 when the shaft 51 is rotated and then release it for operationby the spring 68. The gear ratio between the shaft 51 and the shaft 29is such that the shaft 51 will make one rotation for each gallon ofliquid delivered and the four lobes of the cam 61 being distributedequally about the shaft it will be apparent that the pawl carrier willbe operated four times at equally spaced intervals during the deliveryof each gallon of liquid and will therefore actuate the counterwheel toregister quarts. A second pawl-carrier 69, (Fig. 7) is pivotally andslidably mounted on the shaft 51, and preferably by providing it with alongitudinal slot through which the shaft extends and is provided with anose or pawl 10 to engage and actuate the ratchet wheel 56 for thegallons counterwheel 54. This pawl is arranged on that side of thecounter shaft opposite the pawl carrier 63 and therefore acts on theratchet wheel in an upward direction. A spring 1I tends to move the pawlcarrier upwardly and to hold the pawl in engagement with the ratchetwheel. A one-lobe cam 12 secured to the shaft 51 acts on a projection 13at the lower end of the pawl carrier 69 to retract and release the samefor operation by the spring once upon each complete rotation of theshaft 51, thereby causingthe counterwheel 54 to register the number ofgallons of liquid delivered.

It is desirable that the counterwheels be reset to their initial or zeropositions upon the 'completion of each delivery operation. For thispurpose I have rotatablymounted upon the shaft 51 resetting elements,here shown as resetting gears 14 and 15 which have geared'connectionwith the counterwheels 52 and 54,. respectively, and, 1

in the present instance, mesh directly with gears 16 and 11 formedintegral with the counterwheels. Rotatably mounted on the shaft 51,between the resetting gears 14 and 15, is an actuating element or gear18 and means are provided whereby the rotation of this actuating gearwill cause the resetting gears to be rotated to move the counterwheelsto their initial positions. As here shown, the resetting gears 14 and 15are provided, respectively, with hubs 19 and which extend inwardlytoward the actuating gear and are provided at their inner ends withone-toothed ratchet wheels 8| and 82. It is also desirable that theshaft 51 should be actuated to reset the cams 81 and 12 to their initialpositions. In the present construction I have mounted onthe shaft 51 twosleeves 83 and 83a. The sleeve 83a is rotatable on the shaft and issecured to' andforms a hub for the gear 18, and the hub 80 is rotatablymounted on this sleeve 83a. The sleeve 83 is rigidly secured to theshaft and the 'hub 19 is rotatably mounted thereon. Rigidly secured tothe sleeve 83, between the ratchet wheel BI and the actuating gear 18,is a one-toothed ratchet wheel 84. Pivotall'y mounted on one side of theactuating gear 18 is a spring pressed pawl 85 the nose of which is broadenough to engage the teeth of both the ratchet wheels M and 84, andpivotally mounted on the opposite 'side of the'actuating gear is aspring pressed pawl 88 adapted to engage the ratchetwheel 82.Consequently when the actuating gear is rotated in a forward directionthe pawls will pick up the respective one-toothed ratchet wheels 8|, 82and 84, in whatever positions they may occupy, and restore thecounterwheels and the cams to their initial positions.

The necessary predetermined movement may be imparted to the actuatingdevice 18 in any suitable manner. In the present instance, this isaccomplished by an operating mechanism comprising a shaft 81 providedwith an actuating handle 88 (Fig. 1), and having mounted thereon a gear89 provided with a sufficient number of teeth to impart one completerotation to the actuating gear 18 upon each rotation of the shaft 81. Inthe present apparatus this operating mechanism operates not only theresetting devices but also a printing mechanism, and the gear 89 is amutilated gear of such a character as to permit the completion of theprinting operation before the resetting operation begins. The printingmechanism is no part of the present invention. Briefly it comprises aplaten 90 carried by a lever 9| which is acted uponby a spring 92 tocause the platen to engage an ink ribbon 93, between which and the typefaced counterwheels extends a record strip 94. The platen is heldnormally in an elevated position by means of a cam 95 mounted on a shaft96 above the shaft 81 and connected thereto by gears 91. The cam is soarranged that the first'movement of the shaft 81 will release the platenfor printing movement and a short further movement of'the shaft willcause the cam to lift the platen away from the type wheels. To permit.of this operation of the platen the gear 89 of the operating mechanismis provided with a smooth peripheral portion 98 which contacts with acorresponding part 99 of the actuating gear, this contact serving tohold the actuating gear normally against rotation. When the shaft'81 hasbeen rotated far enough to bring the toothed portion of the gear 89 intoengagement with the teeth of the actuating gear 18 the printingoperation will have been completed and the counterwheeels will be resetto zero.

" Means are also provided to positively limit the movement of the shaft81 to one complete rotation and, as shown in Figs. 2 andll, this meanscomprises a pair of oppositely extending arms I 00 and IOI rigidlysecured to the shaft 81; The arm I00 has in its lower edge a recess I02and the arm IOI has a laterally extending stud I03. Pivotally mountedbelow the arms I00 and MI is a pair of rigidly connected dogs I04-andI05. The dog I04 has a tapered nose adapted to enter the recess I02 inthe arm I00 and to positively stop the movement of the shaft 81. Aspring I06 connected with the dog I05 tends to move the two dogs abouttheir axes and to carry the dog I04 out of line with the arm I00. Whenthe parts are in their normal positions. the end of the doe I04 isseated in the recess and is thus held against movement by the spring.When the shaft 81 is to be operated a short movement is imparted to thecrank 88 in a reverse direction, thus moving the arm I00 out ofengagement with the dog I04 and permitting the latter to be retracted bythe spring, thereby releasingthe shaft for rotation. As the shaftapproaches the end of one complete rotation the stud I03 on the arm IOIwill engage the dog I05 and move'thc dog I04 into line with the recessin the arm I00. The dog I05 is of such length that the stud I03 willclear the same just before the arm I00 contacts with th dog I04 but thetapered end of the dog I04 will have entered the recess I02 before thestud clearsthe dog I05 and the dog is thus prevented from moving out ofline with the arm and the shaft is positively stopped.

In order to prevent the counterwheels from being overthrown by momentumat the end of the resetting operation I have provided means forpositively stopping the movement of the resetting gears at the end ofone complete rotation. (See Figs. 2, 7 and 8.) For this purpose theactuating gears 14 and 15 are provided with parts forming stops, such aslaterally extending pins I01. Pivotally mounted on a fixed part of thestructure, preferably beneath the shaft 81, is a lever I08 which isshown in the form of a bell crank, one arm of which is provided with twoupwardly extending parts I09 arranged to be moved into and out of thepath of the respective pins I01 by the pivotal movement of the lever. Aspring IIO acts on the lever to hold the parts I09 normally out of thepath of the pins. The second arm of the lever extends upwardly and hasat its upper end a nose III arranged to be acted upon by a cam II2 onthe shaft 81; This cam is so arranged that as the counterwheels approachtheir initial positions, during the resetting operation, the lever willbe rocked about its axis and the parts I09 moved into the paths of therespective pins I01 and will be retained there until the counterwheelshave been restored to their initial positions, thus providing a positivestop to interrupt the movement of the counterwheels. At the instant thatthe counterwheels reach their initial positions the cam II2 clears thenose III of the lever and the lever is moved by the spring IIO to itsinoperative position, thereby releasing the resetting gears andcounterwheels for operation.

The mechanism which operates the resetting means for the counterwheelsalso actuates the shaft 29 to reset the indicating devices. As hereshown, a shaft H3 is connected by gears II4 with the shaft 81 forrotation therewith and is also operatively connected with the shaft 29.asmuch as the complete rotation of the shaft 81 is necessary to resetthe counterwheels and the indicating pointers may be returned to theirinitial positions with a less movement of the shaft 81 it is desirablethat the connection between that shaft and the resetting means for theindicating devices should be of such a character as to permit the shaftto continue its rotation after the pointers are in their initialpositions, that is, after the reverse movement of the shaft 29 has beenstopped by the contact of the trip arm with the star wheel. For thispurpose I have interposed between the shaft 81 and the shaft 29 a slipconnection. As here shown, the shaft H3, which is geared to the shaft81, as shown in Fig. 4, is connected with the hub II5 of a plate orsupporting member I I6, which hub is rotatably mounted in a bracket II1.Arranged in line with the shaft H3 is a shaft II8, forming in effect anextension of the shaft H3 and having secured thereto a gear I I9 whichmeshes with a pinion I 30 upon the shaft 29, as shown in Fig. 5. Rigidlysecured to the shaft IIO, adjacent to the supporting member I I6, is afriction drum I2 I. Pivotally mounted on the supporting member I I6arefriction members,

- here shown as a pair of friction shoes I22, which extend about theperiphery of the drum |2I and are pressed into frictional contacttherewith by a spring I28. The frictional contact between the shoes nndthe drum is sufficient to cause the shaft 29 and its associated parts torotate with the shaft 81 but when the movement of the shaft 29 has beenpositively stopped with the pointers in their initial positions theshoes I22 will slip on the drum and permit the further movement of-theshaft 81, when such further movement is.

necessary to complete the resetting of the counterwheels. It isnecessary, however, that the connection between the shaft 29 and theshaft 81 should be interrupted during the delivery operation of theapparatus, to permit the free rotation of the shaft 29 by the meter. Ihave therefore provided means for automatically separating the frictionmembers and thereby disconnecting the shaft II 8 from the shaft IIJ. Inthe construction shown, a cam shaped expanding device I24 is mounted onthe supporting member or plate II6 between the free ends of the frictionshoes I 22 and is provided with a laterally extending arm I25 having atits outer end a head I26. A fixed actuating device is arranged to beengaged by the head I26 of the arm I25 and to cause the latter toactuate the expanding device to move the shoes out of engagement withthe drum when the shaft 81 of the operating mechanism is moved to itsinitial position. This actuating device is shown as a stud I21 mountedon the bracket II1 beneath the friction driving element and so arrangedthat the last portion of the movement of the supporting member or plateII6 by the shaft 81, at the end of the resetting operation, will movethe head I26 onto the stud I21, thereby causing the arm I25 to actuatethe expanding device to move the shoes out of frictional contact withthe drum and releasing the shaft II8 for rotation .by the shaft I29. Thehead I26 remains in engagement with the stud I21 when the movement ofthe shaft 81 is interrupted at the end of the resetting operation, thusrendering the frictional connection between the shaft 81 and the shaft III inoperative during the delivery operation. The first portion of themovement of the shaft 81 upon the next resetting operation will causethe supporting plate I I 6 to move the head I26 of the expanding deviceout of engagement with the stud' before the mutilated gear 89operatively engages the actuating gear 18, thereby permitting the shoesto again grip the drum and connect the shaft 29 with the shaft 81 beforeresetting movement is imparted to the counterwheels.

For the purpose of preventing the operation of the resetting mechanismwhile the delivery mechanism is in operation and for preventing theoperation of the delivery mechanism while the resetting mechanism is inoperation, I have provided an automatic locking mechanism. (See Figs. 1and 4.) The shaft 81 of the operating mechanism for the resetting deviceis extended through the wall of the housing 49 and into the housing I6and has rigidly secured thereto, Jithin the housing I6, a disk I28having a peripheral notch I29, this disk constituting a locking memberrigidly connected with the operating mechanism. A second locking memberis mounted adjacent to the disk I28 and, as here shown, is in the formof a lever I20 one end of which is arranged alongside of the disk I28and is adapted to be moved into the notch I29 when that notch is in linetherewith. The opposite end of the lever is connected by a rod I 3| withthe switch actuating lever 25, the connection being so arranged thatwhen the lever is in its inoperative position, that is, when the switchis open, the locking member I30 will lie alongside of but out ofengagement with the disk I20. If the switch act...

ating lever is moved to its operative position, to close the switch,while the resetting mechanism is in its normal position, the lockingmember I30 will be caused to enter the recess I 29 in the disk I28 andwill thereby lock the resetting mechanism against operation so long asthe switch is closed. If the shaft 81 of the resetting mechanism isactuated while the switch actuating lever is in its open position theunn tched portion of the disk I28 will be moved in line with the lockingmember I30 andthe switch actuating member thus locked in its inoperativeposition until the resetting operation has been completed and the shaft81 restored to its initial position.

While I have shown and described one embodiment of my invention I wishit to be understood that I do not desire to be limited to the detailsthereof as various modifications may occur to a person skilled in theart.
